the artv to which it appertains to make and.

use the same.

. This invention relates to improvements in l combined cotton choppers and cultivating means, and has for an object the arrangement of a hoel or chopper for thinning the cotton, and a toothed rake or auxiliary hoe for cultivating and removing vegetation from around the cotton not removed by the hoe or chopper.

Another object ofthe invention is the arrangement of a solid hoe and a toothed hoe for alternately removing vegetation and re moving apart of -t-he cotton.

Another object of-the invention is the arrangement of a solid hoe for removing part of the cottonv or thinning the same, and a toothed hoe for cultivating the cotton notv removed Vby the solid hoe, in combination with atscraper for the solid hoe and a scraper Ofor the toothed hoe for cleaning the respec tive hoes.

A'still further object of the invention is v thev arrangement of a machine adapted to be'=`drawn across the field .astride of a row of cotton, formed with a solid hoe for'engagingiheiground and removing the cotton at predetermined intervals, and a` toothed hoe for cleaning away vegetation from around the cotton left by the solid hoe, both hoes being self-cleaning and arranged to be ad j-usted instantly'at any time. 5 With these and other objects in view the invention comprises certain novel `constructions, combinations and arrangement of parts-as will be hereinafter more fully described and claimed.- In the accompanying drawings: Figure 1 is aside elevation of the machine, embodying the invention. Fig. 2 is a top plan View of the struct-ure shown in Fig. 1. Fig. 3 is a section through Fig. 2 on line 3-3. Fig. 4 is a section through Fig. 2 on line 4-4 Referring -to the Vdrawing by numerals, 1 indicates a lower frame and 2 an upper frame connected by a plurality of cross members and supported upon axle 3 carrying traction wheels 4 and 5. The front ends of the frames'l and 2 are supported by wheels 6 and 7 and conneetin mechanism hereinafter more fully describe The lower frame 1 is connected withy journal members 8 land 9which=membersperm`it a-free rotation of axle Wheels 4 and v5 are rigidly secured to axleys'o as to positively rotate thejsame when themachine is being moved.

'Axle 3 has rigidly secured thereto abeveled gear 10 meshing with beveled gear 11, which is rigidly secured to a shaft 12. Shaft 12 is journaled in across bar 13 which in turn is rigidly secured to frames 1 and 2 and acts as a brace therefor. Shaft 12 carries at thecommodating a chain 15 which passes over a second sprocket 16 rigidly secured to fa crank shaft 17. Positioned on the chain 15 is a tension roller 15 mounted on a shaft 16 journaled in the lower ends of the extensions 17 which are secured to oneof the lower frame bars. Crank shaft 17 is supported by brackets 18, 19 and 20, which are secured to frames 1 and 2. Crank shaft 17 is formed with crank members 21 and 22, crank member 21 having pivotally connected therewith a pitman 23 which carriesa solid hoe 24,

and crank member 22 having pivotally connected therewith a'pitman 25 that carries a toothed hoe 26, crank members 21 and 22 -being arranged to work 1n opposition to each end opposite gearL 11 a sprocket 14 for acother. Pitman 23 is designed to be mounted so as to operate without lateral adjustment in frames 1 and 2, while pitman 25 is mounted so as to be adjustable toward or from pitman 23, in order to vary the action of hoe26 in respect to hoe 24. In order to permit this adjustment,`crank member 22 is made comparativel;v long and has mounted thereon sleeves 27 and 28 which are adjustable thereon. 'Sleeves 27 and 28 may be rigidly held in place by any desired means, as for instance by set screws, so as to hold pitman 25 from any lateral movement, but permit a free pivotal movement thereof. The end 'of pitman 25'opposite crank member 22 passes through a pivotally mounted guiding member 29 which is pivoted in a guiding frame 30 which in turn is slidably mounted upon al rod 31. Rod 31 is conneoted'to cross bars 32.

and 33, which are pivotally mounted upon l-justing rod 34. Rod 34 has a link 35 connected therewith, which in turn is connected with a crank arm 36. Crank arm 36 is formed integral with or rigidly connected with a cross bar 37 and has formed on the opposite side thereof a crank 33 (Fig. 1),to which is pivotally secured a 'link 39. Link 39 is pivotally connected with a lever 40, which is adapted to beoperated by an operator upon seat 41. By this means whenever the operator on seat 41 desires to raise or lower the framework, comprising cross bars 32 and 33, all that will be necessary is to move leve'r 40 forward or backward. As the toothed hoe operates, this adjustment will' vary the distance which the teeth will engage the earth for eitherculti vating the soil or merely removing the trash and vegetation above the earth; Connected with bars 32 and 33 is a toothed cleaner 42 which is designed to remove the dirt and -trash from hoe 26 at each complete cycle thereof. Cleaner 42 is raised and lowered together with bars 32 and 33 so as to be always in proper relationship to hoe 26.

VThe pitman 23 of solid hoe 24 is slidably mounted at its outer end in a pivotal bearing' 43. Bearing 43 is pivotally mounted in a framework 44 which in turn is pivotally connected to bars 45 and 46 which extend across the machine and are pivotally mounted upon crank shaft 17. Framework 44 is connected with an adjustable sliding bar 47 which is pivotally connected with a lever 48. Lever 48 is pivotally connected at 49 to frame 2 at one end and to a link 50 at the opposite end. Link 50 is] pivotally connected with a lever 51 so that whenever le- -ver 51 is moved forward or rearward bar 47 will be raised' and lowered for controlling the elevation of hoe 24.

In connection with solid hoe 24 a cleaner 52 is provided for scrapingoff any dirt or foreign matter therefrom upon each move ment thereof. Cleaner 52 is pivotally mounted at 53-53 upon bars 45 and 46. The cleaner 52 is formed with an arm 54 which has pivotally connected therewith a link 55 which in turn is connected with a crank 56. Crank 56 is journaled in bearings 57 and 58, and --has formed on the outer end thereof a handle 59 which may be grasped by the operator upon seat 41 for moving cleaner 52 toward or from hoe 24.

By the construction and arrangement of. means set forth, whenever the machine is drawn across the field astride of a row of cotton-power will be transmitted from wheels 4 and 5 to the hoes 24 and 26 which will clean, and also thin the cotton by removing short sections thereof. The movement of the hoes is on the order of the movement of an ordinary hoe in use by a person, so as to give a shearing action for cutting away the matter desired to be moved.

If desired an ordinary draftappliance may be provided at the front end of the mavehine,'to which may be secured any desired power for moving the-machine across the lever 65 pivoted at 66. Lever 65 has pro.

jecting from the lower side thereof a projection or tooth 67 for engaging the teeth in rack 68 for holding lever 65 in any desired position'. connecting and operating bar 69 is pivotally connected with lever 65 and extends to the rear ofthe machine and is formed with a gripping member 70 in proximity to the seat 41. Bod 69 passes through a guiding member 71A which also may be used as a fu'lcrum by which lever 65 may be raised out of engagement with rack 68 so as to be more freely movable therefrom. By this arrangement whenever the machine is not correctly located over a row of cotton the operator on seat 41 may move gripping member 70, and transmit motion to upright 60, and from thence to axle 71 to which it is secured. Axle 71 carries wheels 6 and 7 which support the forward end of the machine. As the axle 71 is moved pivotally by these means wheels 6 and 7 are set at an angle to the general direction of the'chopper, so that a continued movement o'f the machine will move the same laterally until the machine is moved back to its correct position, after which the axle is again turned to take a posit-ion at right angles to the row of cotton in order that the further movement of the machine will be correctly over the row of cot-ton. By this means any slight lateral movement ofthe machine desired may be accomplished without changing the drafting power.

Connected with brackets 61 and 62 isa hitchin bar 72 to which may be secured the power or drawing the machine across the field. Hitehing bar 72 is providedv with a plurality of apertures for hitching the power at any desired height as occasion may require.
